Charles J. Henny
I am a Scientist Emeritus at the USGS Forest and Rangeland Ecosystem Science Center.
My research focuses on field studies of raptors and fish-eating birds, particularly Ospreys. I am interested in the unique situations and characteristics that make particular species vulnerable to contaminant threats. In my spare time I enjoy collecting bird books.

A reward band study of mallards to estimate band reporting rates A reward band study of mallards to estimate band reporting rates
Reward bands ($10) were placed on 2,122 hatching-year mallards (Anas platyrhynchos), and an additional 11,490 received conventional bands (controls) to estimate band reporting rates. An analysis of band recoveries indicated that the reporting rate was dependent primarily upon three factors: (1) the distance banded birds were recovered from the banding site, (2) band collecting activities...

Thermal adaptiveness of plumage color in screech owls Thermal adaptiveness of plumage color in screech owls
Clinal variation in the relative proportions of red and gray plum- age phases in Screech Owls (Otus asio) was analyzed by Owen (1963) and Marshall (1967). This variation was well known prior to Owen's work, but was misinterpreted (Baird, et al. 1874, Hasbrouck 1893, Allen 1893).] Laurel VanCamp and Charles Henny (MS) have 30 years of data on a northern Ohio Screech Owl population. They...

Biochemical identification of the mallard, Anas platyrhynchos, and black duck, A. rubripes Biochemical identification of the mallard, Anas platyrhynchos, and black duck, A. rubripes
1. Eleven tissue systems from mallards and black ducks were examined for soluble proteins, lactate dehydrogenases and non-specific esterases through discontinuous polyacrylamide techniques. 2. Biochemical relationships between the black duck and mallard are extremely similar. 3. Hemoglobins and lactate dehydrogenase appear to be common in electrophoretic mobility between the two species...
